Hello,

Every time i play a vidéo, i have to resynchronize audio and video because of a 1/2 second lag making the audio play before the video.

What could be the cause of the gap ?

How about sharing your audio settings? So many variables and combinations and you have supplied no information for anyone to be able to help you apart from taking a guess.

Also see the instructions on supplying a Debug Log - this provides users with a great amount of detail to be able to aid answer your query.
